Itโs officialโB&ZAI is heading to OSAKA GIGANTIC MUSIC FESTIVAL 202!

The Junior group B&ZAI has been announced as one of the featured acts for OSAKA GIGANTIC MUSIC FESTIVAL 2025, set to take place on July 19โ20 at the Expo โ70 Commemorative Park in Osaka. With their appearance slated for Day 2 (July 20), B&ZAI will share the stage with major names like MY FIRST STORY, 04 Limited Sazabys, BLUE ENCOUNT, and PassCode, among many others.
OSAKA GIGANTIC MUSIC FESTIVAL, or JaiGa (ใธใฃใคใฌ), as it’s lovingly known, is one of Kansaiโs biggest summer festivalsโlast year attracting a crowd of 55,000 fans over two days. This yearโs lineup is just as stacked, and B&ZAIโs inclusion in the fourth wave of artist announcements feels like a well-earned milestone for a unit that’s been steadily gaining momentum and interest since their formation after the Junior re-shuffle..
Having already turned heads with bold performances in their previous formations, the members of B&ZAI are now carving out a new identity that is sure to blend expressive performances, magnetic stage presence, and a genre-crossing sound that cuts through even the most packed festival lineups.
But their appearance at JaiGa isnโt just another performanceโitโs a statement. This is a group made up of familiar faces from across the STARTO universe: former 7 MEN Samurai members Rinne Sugeta, Katsuki Motodaka, Taiki Konno, Rei Yabana, Shonen Ninja members Hoshiki Kawasaki, Michiharu Inaba, Yujin Suzuki, and Ryo Hashimoto of HiHi Jets. While each member has earned recognition through their previous groups or solo activities, B&ZAI is a fresh startโborn from ambition, artistry, and the belief that they have something new to offer together.
Each member brings a unique strength to the mix, but their shared goal is clear: to redefine what STARTO idols can be in the modern music sceneโnot just as performers, but as musicians and entertainers in their own right. JaiGa is only the beginning.
